Knowing your microphone
Superlux provides a wide variety of microphones for both professionals
and amateurs. Knowing the audio characteristics of your microphone is
the first step to a successful result in audio reproduction. The
following text gives some information on the characteristics of the
E302 microphone and its care:
About Frequency Response
Flat
A measurement microphone needs a response that is as flat as possible in
order not to give any coloration to the sound source. The E302 is
designed specifically to give this desired flat response.
Directivity/ Omni-directional Polar Pattern
A measurement microphone should have an omni-directional polar
pattern to capture the sound from all directions, just like the
human ear. The E302 has equal sensitivity in all directions,
making it unnecessary to point the microphone directly toward the
sound source when in use.
Transducer Type
Condenser
A condenser microphone features an extremely lightweight diaphragm
which is very sensitive to sound. High performance condenser
microphones are regarded as standard equipment in recording studios
for their ability to capture the finest acoustic detail and very small
versions are available for applications where visual minimalization is
desirable. A condenser microphone requires a power source such as
phantom power or a battery for its operation. The E302 can be
powered directly from the microphone input of a laptop or PC,
giving it great flexibility in use.
Microphone Placement
Place the E302 measurement microphone at the “best seat”¨
measurement data. If the audience area is large, you may prefer to get
the average from several of the best locations.
Maintenance
Condenser microphones should be kept in a low humidity
environment for the best sound performance. Store condenser
microphones in an air conditioned room or one equipped with a
dehumidifier to keep them away from moisture. Clean air is another
important factor. Keep the microphone away from a smoking
environment to avoid tar residuals which could potentially affect the
sensitivity of the microphone.
Extraneous Noises
The E302 features low handling and wind noise, making it ideal for
news gathering, music recording and measurement applications.
